Surface density of dark matter haloes on galactic and cluster scales [PDF]

, 2012
In this paper, in the framework of the secondary infall model, the correlation between the central surface density and the halo core radius of galaxy, and cluster of galaxies, dark matter haloes was analyzed, this having recently been studied on a wide ...

First stars IV. CS 29497-030: Evidence for operation of the s-process at very low metallicity [PDF]

, 2003
We present an abundance analysis of the very metal-poor, carbon-enhanced star CS 29497-030. Our results indicate that this unusually hot turno star (Te = 6650 K, logg= 3.5) has a metallicity (Fe/H)= 2:8, and exhibits large overabun- dances of carbon ((C ...

A multispectral view of the periodic events in η Carinae [PDF]

, 2007
A full description of the 5.5-yr low excitation events in η Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two components.

Two formation channels of UCDs in Hickson Compact Groups [PDF]

, 2010
Context. The formation of ultra-compact dwarf galaxies (UCDs) is bel ieved to be interaction driven, and UCDs are abundant in the cores of galaxy clusters, environments that mark the end-po int of galaxy evolution.

H2 infrared line emission from the ionized region of planetary nebulae [PDF]

, 2010
Context. The analysis and interpretation of the H2 line emission from planetary nebulae have been done in the literature by assuming that the molecule survives only in regions where the hydrogen is neutral, as in photodissociation, neutral clumps, or ...
